evaluation of the extent of among Family variation in inbreeding depression in the perennial herb scabiosa columbaria dipsacaceae
American Journal of Botany, 2004Co-Authors: Xavier F Pico, Joop N Ouborg, Jan M Van GroenendaelAbstract:Significantly different maternal line responses to inbreeding provide a mechanism for the invasion of a selfing variant into a population. The goal of this study was to examine the extent of Family-level variation in inbreeding depression in the mixed-mating, perennial herb Scabiosa columbaria. Plants from one population were raised, and hand-pollinated to produce selfed and outcrossed progeny, and the effects of inbreeding depression on life-cycle traits were analyzed. Inbreeding depression significantly affected early life cycle traits. The pollination treatment by Family Interaction was significant for almost all traits, indicating a high Family-level variation in inbreeding depression. The correlations between inbreeding depression values (e.g., percentage germination and flowering date, and flowering date and aboveground biomass) exhibited alternate signs, illustrating the type of association between inbreeding depression loci for different traits across the life cycle. Overall, it is concluded that the extent of among-Family variation in inbreeding depression might allow a selfing variant of S. columbaria to invade an outcrossing population, though the pattern of correlations between inbreeding depression values might prevent effective purging of the deleterious genetic load.

the role of Family Interaction in new immigrant latinos civic engagement
Journal of Communication, 2009Co-Authors: Holley A Wilkin, Katz Vikki S, Ballrokeach J SandraAbstract:Civic engagement can impact politics, health outcomes, support for new policies, and the like. Research indicates that the communication infrastructure and the strength of the storytelling network, influences civic engagement outcomes. Recent community building initiatives place the impetus of community change and civic engagement on the Family unit. This paper places the Family unit within the storytelling network and explores how Family Interaction is related to civic engagement. A telephone survey of 739 new immigrant Latinos in Los Angeles was used to test the effect of Family Interaction on civic engagement. Regression analyses, controlling for sociodemographic factors, were used. Results indicate that Family Interaction leads to higher levels of civic engagement and encourages more integration into the neighborhood storytelling network.
